The Sikorsky S58 was one of the most successful piston powered mid size helicopters built. Sikorsky developed the S58 in response to a US Navy requirement for an anti submarine warfare helicopter. What resulted was the S58, which features a single Wright R1820 radial piston engine mounted in the nose, one of the largest fuselages to be designed for a single piston powered halo and a raised flightdeck.
Large numbers of S58s were subsequently built to serve with the US Navy in anti submarine warfare roles as the SH34G and SH34J Seabat, and in utility roles with the US Marines as the UH34D Seahorse. The US Army operated large numbers as the CH34 Choctaw while many other allied countries operated the S58 in various military roles.

The UK for example license built a turboprop development called the Wessex, some of which saw civil service. Modest numbers of piston powered S58s saw civil service with most were delivered to customers within the USA. The S58 offered a very large fuselage and lifting capacity, but its piston engine made it expensive to operate. |
